When rubbing a balloon with a wool cloth, it puts negative charges on the balloon. Negative charges attract to positive charges. When both balloons are rubbed with the wool cloth, the both receive negative charges, so they will repel each other.

When a balloon is rubbed on hair, electrons are moved from the hair to the surface of the balloon. When a balloon is rubbed on hair, fur or wool, electrons are moved from the hair to the balloon, giving the balloon a negative charge.

When you rub a balloon with a wool cloth, the balloon captures electrons from the wool, leaving the balloon with a negative charge and the wool with a positive charge. If both balloons are rubbed with wool, they will both have same charge (negative) and therefore will repel each other.

If you rub a polythene rod with a woolen cloth, electrons are transferred from wool towards the surface of the polythene rod. The woolen cloth now has more positive charges than negative charges and so it becomes positively charged while the polythene rod becomes negatively charged.

When a wool cloth is rubbed on a plastic comb, the cloth loses electrons and the comb gains them. The comb now has a negative charge and the wool has a positive charge.

Wool is a conductive material, which means it readily gives away its electrons. Consequently, when you rub a balloon on wool, this causes the electrons to move from the wool to the balloon’s surface.

Answer: If the plastic ruler is rubbed vigorously with a woolen cloth, then they get both positively and negatively charged. Explanation: When the ruler is rubbed with a woolen cloth, the ruler will get a positive charge and the woolen cloth will get a negative charge.

The balloon becomes charged when rubbed with wool. It is attracted to the uncharged wall. The balloon often sticks for hours because the electrons do not move very well on the balloon. The charged comb attracts the uncharged stream of water.

When you bring the negatively charged balloon close to the stream of water, the hydrogen end is attracted towards the balloon and the oxygen end is repelled away from it. This pair of forces twists the water molecule so that the line from the negative pole to the positive pole points towards the balloon.

When you rub a balloon on your head, electrons move from the atoms and molecules in your hair onto the balloon. Electrons have a negative charge, so the balloon becomes negatively charged, and your hair is left with a positive charge.

A charged object attract small particles, such as dust. The charge in the object causes a complementary charge to develop in something close to it. The charge on the comb attracts the molecules of water in the stream. Because the molecules in the stream can be moved easily, the stream bends toward the comb.

Oxygen can also exist as a radical, such as where an oxygen atom has one bond, two lone pairs, and one unpaired (free radical) electron, giving it a formal charge of zero.

Explanation: Oxygen atoms have 8 protons and 8 electrons. Two electrons are located in the first energy level, and 6 electrons are located in the second energy level. By adding two electrons to the second energy level, a more stable noble gas electron configuration is achieved by the oxygen.

Because electrons have a charge of 1-, adding two electrons would make the charge of the oxide ion 2-. Oxygen takes the electron density from other atoms when it forms two bonds, to become a negative two ion.

1 Answer. Dioxygen gas, O2 , the stuff we are breathing now…is NEUTRAL…..

An element from group 17 wants to gain an electron to from a negative ion. A metal forms only positive ions, an element from group 1 will lose to form a positive ion and elements with eight valence electrons are normally very stable, meaning they don’t need to lose or gain.

1 Answer. The elements that are most likely to form 2− ions are the group 16 elements. Their atoms have 6 valence electrons, and need 2 more to have a full valence shell of 8 electrons in order to become stable. When they gain 2 electrons in order to have 8 valence electrons, an octet, they gain a 2− charge.
